You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7

n= -2
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
9y subtract 11 equals 7
You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7
2x+3 = -11 2x = -11-3 2x = -14 x = -7
7
11 + 7 + 9 = 27

-7 + 11 = +4
n= -2
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
p is obviously zero because any number x plus 0 equals itself.
x=7
